Application led September 23, 1915. Serial No. 52,265.

To all whom t may concern Be it known that I, WILLIAM C. CRAFT, a

citizen of the United States, residin at St.

Paul, in the county of Ramsey and tate of Minnesota, have invented a newand useful Improvement in Repair-Patches, of which the following is aspecification.

- This invention relates to an improved repair patch for vehicle coversand curtains,

the primary obj ect being to provide a strongand durable patch, whichcan be quickly attached, and which will hold securely and ofconstruction and combination of permanently when attached to thematerial constituting the covers or curtains of ve' hicles.

A further object is to which can be easily applied without the use of,tools and which will hold without creeping, loosening or leaking.

A still further object is to provide a patch which can be easily usedwhen cold, and without the application of heat. To these ends myinvention comprises the features parts hereinafter described andclaimed.

The accompanying drawing is a section of a detail of my improved'repairpatch.

Automobile tops comprising thecover and side curtains are usuallycovered with water proofed fabric, such as whaty is commonly.

called mohair or pantesote. This material is usually made out of canvas,cotton or linen fabrics or other materials constituting a backing andsaid backing is usually coated on the outside with a thin layer of waterproof material made of rubber or suitabley composition. In repairing anyholes or breaks in this material, it is laborious as well as expensiveto sew patches over the broken portions, and my. inventlon obviates thisobjection by providing a patch which can` bequickly attachedpermanentlyover the broken portion of the coverin This patch which Ihave vinvente comprises a backing of material of a somewhat similarnature to that employed in the lcover and curtains of the top. l

In the drawing A indicates said bacln'ng which vis composed of textilematerial, such for instance as canvas 2 having an outer water proofedsurface 3 of rubber or other composition intimately united therewith:provide apatch i from its-v adhesive surface.

The under-surface of thisbacking is coated with a thin layer of rubber 4, which is secured to thesurface of the backing by pressure or by f pressure and heatingresulting in a unitary structure being provided having an outer waterproofed surface and an inner adhesive surface, .which is to be securedover the broken part of the cover or curtain when' repairing the same.To protect the surface of the rubber 4c before application to the coveror curtain to be repaired, a thin fab# ric is pressed tightly over itssurface, said fabric 5 being composed of any thin textile suitably waxedor treated to produce a protective medium and prevent air from cominginto contact with the surface i of rubber until the patch is used. Y

lIn use the patch is made of the desired area and shape and the cover 5stripped The adhesive side of the patch is then applied over the brokenportion of the cover or curtain and ibut usually it is preferabletoemploy cement.
